There are poor water circulating pump, described poor water circulating pump one end to be connected by the bottom water outlet of pipeline and rectifying column, the other end passes through pipe
Road connection setting Heat Exchanger in Circulating Water System, the treating column side be equipped with treating column water reboiler, the side ports of the treating column with
The top port for the treatment of column water reboiler connects, and the bottom port for the treatment of column water reboiler and the bottom port for the treatment of column connect,
To constitute circulation loop；The pipeline connected between the poor water circulating pump and Heat Exchanger in Circulating Water System is equipped with bye-pass, described
Poor water circulating pump is connect by bye-pass with the lower side port for the treatment of column water reboiler, and heat source is provided for treating column water reboiler.
The purification ethylene oxide tower heating system, which is characterized in that poor recirculated water in the poor water circulating pump
Temperature is controlled at 130-140 °C.
The purification ethylene oxide tower heating system, which is characterized in that be equipped at the top of the Heat Exchanger in Circulating Water System external
The upper side port of pipeline, the treating column water reboiler is converged and is connected by the external pipeline at the top of pipeline and Heat Exchanger in Circulating Water System
It is logical.
The utility model has the beneficial effects that；
1）Treating column uses treating column water reboiler heat supply in the system, and treating column water reboiler heat source is by poor water circulating pump
Interior poor recirculated water provides, and treating column can be made to have saved a large amount of thermal energy for steam without using outer, reached energy-saving and environment-friendly mesh
, while improving the economic benefit of production.
2）It uses poor recirculated water to provide as heat source, reduces the discharge capacity of steam condensate, reduce sewage disposal system
Burden, while improving economic benefit.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure：1- rectifying columns, the poor water circulating pumps of 2-, 3- Heat Exchanger in Circulating Water System, 4- treating column water reboilers, 5- treating columns,
6- bye-passes.
Specific implementation mode
Below in conjunction with Figure of description, the utility model is further described.
As shown in Figure 1, purification ethylene oxide tower heating system, including rectifying column 1, poor water circulating pump 2, Heat Exchanger in Circulating Water System
3, treating column water reboiler 4, treating column 5 and bye-pass 6.1 bottom of rectifying column is equipped with poor water circulating pump 2, the poor water circulating pump 2
